AWMA were engaged by Seymour Whyte Constructions for the Melbourne Water Upper Yarra Dam Upgrade.
The water control gates isolate flow into the seepage weir structure at the toe of the dam, for maintenance purposes.
Four large marine grade aluminium Bulkhead gates and frames were manufactured and supplied up to 2300mm aperture width, 3100mm high. The Bulkhead gates are inserted into permanently installed frames to isolate flow in the Dam seepage weir structure. The Bulkheads were designed with integral Butterfly and Ball Valves for the equalisation of head pressure following maintenance isolation.
AWMA also supplied a top sealing TLF Penstock for bypass flow isolation. The penstock was custom designed 1200mm wide x 1700mm high, to withstand 3m operating head pressure, on and off seating.
